Health Risks From Dead Bodies
The health risks of dead bodies are dangers related to the improper preparation and disposal of cadavers. While normal circumstances allow cadavers to be quickly embalmed, cremated, or buried; natural and man-made disasters can quickly overwhelm and/or interrupt the established protocols for dealing with the dead. Under such circumstances, the decomposition and putrefaction of cadavers goes unchecked, and raises a series of health, logistical, and psychological issues. After disasters with extensive loss of life due to trauma rather than disease—earthquakes, storms, human conflict, etc.—many resources are often expended on burying the dead quickly, and applying disinfectant to bodies for the specific purpose of preventing disease. Specialists say that spraying is a waste of disinfectant and manpower, that "resources that should be going into establishment of water supply, sanitation, shelter, warmth and hygienic food for the survivors are being applied to digging mass ...

Cadavers
A cadaver, often known as a corpse, is a dead human body. Cadavers are used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students. In addition, a cadaver may be used in the development and evaluation of surgical instruments. The term ''cadaver'' is used in courts of law (and, to a lesser extent, also by media outlets such as newspapers) to refer to a dead body, as well as by recovery teams searching for bodies in natural disasters. The word comes from the Latin word ''cadere'' ("to fall"). Related terms include ''cadaverous'' (resembling a cadaver) and ''cadaveric spasm'' (a muscle spasm causing a dead body to twitch or jerk). A cadaver graft (also called “postmortem graft”) is the grafting of tiss ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mass Grave
A mass grave is a grave containing multiple human corpses, which may or may Unidentified decedent, not be identified prior to burial. The United Nations has defined a criminal mass grave as a burial site containing three or more victims of execution, although an exact definition is not unanimously agreed upon. Mass graves are usually created after many people die or are killed, and there is a desire to bury the corpses quickly for sanitation concerns. Although mass graves can be used during major conflicts such as war and crime, in modern times they may be used after a famine, epidemic, or natural disaster. In disasters, mass graves are used for infection and disease control. In such cases, there is often a breakdown of the social infrastructure that would enable proper identification and disposal of individual bodies. Background Definitions Many different definitions have been given. The Bournemouth Protocol on Mass Grave Protection and Investigation focuses on circumstan ...

Registered Nurse
A registered nurse (RN) is a healthcare professional who has graduated or successfully passed a nursing program from a recognized nursing school and met the requirements outlined by a country, state, province or similar government-authorized licensing body to obtain a nursing license or registration An RN's scope of practice is determined by legislation and job role, and is regulated by a professional body or council. Registered nurses are employed in a wide variety of professional settings, and often specialize in a field of practice. Depending on the jurisdiction, they may be responsible for supervising care delivered by other healthcare workers, including student nurses, licensed practical nurses, unlicensed assistive personnel, and less-experienced RNs. Registered nurses must usually meet a minimum practice hours requirement and undertake continuing education to maintain their license. Furthermore, certain jurisdictions require that an RN remain free from serious crim ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Putrescine
Putrescine is an organic compound with the formula (CH2)4(NH2)2. It is a colorless solid that melts near room temperature. It is classified as a diamine. Together with cadaverine, it is largely responsible for the foul odor of Putrefaction, putrefying flesh, but also contributes to other unpleasant odors. Production Putrescine is produced on an industrial scale by the hydrogenation of succinonitrile. Biotechnological production of putrescine from a renewable feedstock has been investigated. A metabolically engineered strain of ''Escherichia coli'' that produces putrescine at high concentrations in glucose mineral salts medium has been described. Biochemistry Spermidine synthase uses putrescine and S-Adenosylmethioninamine, ''S''-adenosylmethioninamine (decarboxylated S-Adenosyl methionine, ''S''-adenosyl methionine) to produce spermidine. Spermidine in turn is combined with another ''S''-adenosylmethioninamine and gets converted to spermine. Putrescine is synthesized in small q ...

Cadaverine
Cadaverine is an organic compound with the formula (CH2)5(NH2)2. Classified as a diamine, it is a colorless liquid with an unpleasant odor. It is present in small quantities in living organisms but is often associated with the putrefaction of Tissue (biology)#Animal tissue, animal tissue. Together with putrescine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors. Production Cadaverine is produced by decarboxylation of lysine.Wolfgang Legrum: ''Riechstoffe, zwischen Gestank und Duft'', Vieweg + Teubner Verlag (2011) S. 65, It can be synthesized by many methods including the hydrogenation of glutaronitrile and the reactions of 1,5-dichloropentane. History Putrescine and cadaverine were first described in 1885 by the Berlin physician Ludwig Brieger (1849–1919). It was named from the English adjective ''cadaverous''.

Groundwater
Groundwater is the water present beneath Earth's surface in rock and Pore space in soil, soil pore spaces and in the fractures of stratum, rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is Groundwater recharge, recharged from the surface; it may discharge from the surface naturally at spring (hydrosphere), springs and Seep (hydrology), seeps, and can form oasis, oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction water well, wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought o ...

Gastroenteritis
Gastroenteritis, also known as infectious diarrhea, is an inflammation of the Human gastrointestinal tract, gastrointestinal tract including the stomach and intestine. Symptoms may include diarrhea, vomiting, and abdominal pain. Fever, lack of energy, and dehydration may also occur. This typically lasts less than two weeks. Although it is not related to influenza, in the U.S it is sometimes called the "stomach flu". Gastroenteritis is usually caused by viruses; however, gut bacteria, parasites, and fungus, fungi can also cause gastroenteritis. In children, rotavirus is the most common cause of severe disease. In adults, norovirus and ''Campylobacter'' are common causes. Eating improperly prepared food, drinking contaminated water or close contact with a person who is infected can #Transmission, spread the disease. Treatment is generally the same with or without a definitive diagnosis, so testing to confirm is usually not needed. For young children in impoverished countries, pre ...

1918 Flu
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus. The earliest documented case was March 1918 in Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it the deadliest pandemic in history. The pandemic broke out near the end of World War I, when wartime censors in the belligerent countries suppressed bad news to maintain morale, but newspapers freely reported the outbreak in neutral Spain, creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological data make the pandemic's geo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could poten ...

Ebola
Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. Symptoms typically start anywhere between two days and three weeks after infection. The first symptoms are usually fever, sore throat, muscle pain, and headaches. These are usually followed by vomiting, diarrhoea, rash and decreased liver and kidney function, at which point some people begin to bleed both internally and externally. It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between 6 and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start.Ebola in Uganda: An Ebola vaccine was approved by the US FDA in December 2019. The virus spreads through direct contact with body fluids, such as blood from infected humans or other animals, o ...

Contagious Disease
A contagious disease is an infectious disease that can be spread rapidly in several ways, including direct contact, indirect contact, and droplet contact. These diseases are caused by organisms such as parasites, bacteria, fungi, and viruses. While many types of organisms live on the human body and are usually harmless, these organisms can sometimes cause disease. Some common infectious diseases are influenza, COVID-19, ebola, hepatitis, HIV/AIDS, Human papillomavirus infection, Polio, and Zika virus. A disease is often known to be contagious before medical science discovers its causative agent. Koch's postulates, which were published at the end of the 19th century, were the standard for the next 100 years or more, especially with diseases caused by bacteria. Microbial pathogenesis attempts to account for diseases caused by a virus. Historical meaning Originally, the term referred to a ''contagion'' or disease transmissible only by direct physical contact. In the mode ...
